PickleDB

PickleDB is a fast, easy-to-use, in-memory Python key-value store. Key features include:

• High Performance: Built with the orjson module for extremely high performance.
• Async Support: Provides first-class asynchronous support.
• Persistence: Stores data in JSON format.
• License: BSD three-clause license.

PickleDB is a high-performance, in-memory Python key-value store that supports asynchronous operations. It uses orjson for fast serialization and can persist data to a file. To use it, instantiate PickleDB with a filename, call .load() to initialize the database from the file, and use .set() and .get() to manage data.

from pickledb import PickleDB

# Initialize and load the database from a JSON file
db = PickleDB("example.json").load()

# Set a value
db.set("key", "value")

# Retrieve a value
print(db.get("key"))  # returns "value"
